CONTROL FUNCTIONS AND CONNECTIONS A A-Phase Control Switch & LED - This switch allows the user to invert the system phasing easily and safely. The switch is set automatically to the 0° position where the SFD-2 MKII will put out a normal or non-inverted signal in relation to the signal being received from the source. Pushing the switch will put out an inverted version of the signal as compared to that being received from the source.
L G H I G-Detachable Power Cord Socket - Plug the Detachable Power Cord into this socket (see Figure 1). The SFD-2 MKII is factory set for the correct operating voltage for the area in which it is sold (see shipping box for voltage setting). If a different operating voltage is required, please contact an authorized Sonic Frontiers dealer, distributor or the factory directly.
INSERTION OF THE TUBES OPERATION OF THE SFD-2 MKII DIGITAL PROCESSOR The SFD-2 MKII comes with two 6922 (6DJ8-type) tubes, individually boxed and bagged along with a cotton glove, screwdriver, and screws for fastening the SFD-2 MKII cover. If desired, replacement of these tubes may be done to suit the listener’s preference.
TROUBLESHOOTING The SFD-2 MKII Digital Processor is now ready for operation. Power the unit by placing the Power Switch (F) in the OPERATE position. As soon as the SFD-2 MKII is plugged in and switched to OPERATE, the Power Indicator LED will flash on and off for approximately 45 seconds. During this time, the signal outputs are muted while the two 6922 tubes are warming up and stabilizing. As soon as the Power Indicator LED stops flashing and lights green, the SFD-2 MKII is ready to play.
